“I’m sorry, Dave, I can’t allow you to listen to Coldplay.”

What would radio be like if playlists were not only robotic, but had robot DJs pulling information from the Interwebs dynamically? That’s the question asked by the winning team at London’s Music Hackday last weekend, which created an epic mashup of data sources to produce a voice-synthesized IRC chatbot that researches and plays music for you.

Music Bore

Music Bore was just one of a number of projects developed in the weekend of musical hacking, some for listening, and at least one (a fantastic and free synth plug-in) for what we really like – production. With some of the world’s top musical coders in attendance, the results were amazing, even if not all projects were entirely finished. (Hey, that’s why they call it hacking.)

You can check out the full list on the wiki, but here are some favorites — and if you were there, do shout out to us as you put more documentation up of the event and projects.

News may filter through Boing Boing, Slashdot, and Reddit – and certainly, this story already has. But oddly, I learned of this item when I happened to meet up with the blog item’s author in Somerville, Massachusetts. He has digital analysis he believes may prove that a track was recorded to a click track.

Paul Lamere is a developer at Echo Nest, a brainy think-tank of music geeks developing new ways of processing musical metadata in the cloud. Whereas services like Last.fm focus mainly on content and community, Echo Nest’s API wants to make the computers in the cloud smarter about how they listen to your music. We’ve had a look at their work twice before:

Musical Brain API: An API for Music on the Web – And it Makes Pretty Pictures

The Remix API crunches data about rhythmic information at a number of levels. Since we first saw it, that API has led to an SDK (read: something you can program more directly), all assembled in Python. The Python-based SDK is now capable of creating the world’s most unlistenable mash-ups, among other things – some oddly compelling. On Friday, I got to listen to tunes with every other eighth note removed and Michael Jackson crossed with tunes – that is, until the programmers in the office started to complain because they were about to lose their mind. (Echo Nest uses a Sonos system to pipe music office-wide. I hope we can give you a preview of those clips soon.)

But perhaps the most interesting thing this team has done so far is Paul’s work on plotting rhythmic analysis. Plots of tempo deviation, measured in beat durations, yield two interesting revelations:

1. Much of the music you know has a lot of rhythmic variation. (Dizzy Miss Lizzie by the Beatles, anyone? No Ringo Starr jokes, please.)

2. A lot of the other music has disturbingly little rhythmic variation.
